All auras in game use the same cooldown timer. If you hit one, all others became unavailable. This pretty much kills variety, as everyone spare aura timers for MPA and thus rarely use anything else. However other auras such as War Cry or regen ones could get more use if they won't crossover with MPA. I suggest to put every aura on its own timer and give players more flexibility in choosing what action to use according to situation.
